Description

Technical Field

[0001] This utility model belongs to the field of electroplating hanger technology, specifically relating to a hanger suitable for heavy items. Background Technology

[0002] Traditional hangers often employ simple hooking or clamping methods when suspending heavy shafts. This approach has several problems. First, the connection strength is insufficient; during lifting, the weight of the shaft can easily cause the hanger to loosen or even detach, disrupting electroplating processes and potentially causing safety accidents. Second, traditional hangers have an unreasonable structural design, poor component coordination, and cannot effectively utilize the weight of the suspended object to enhance connection strength. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides the following technical solution: a hanging device suitable for heavy items, comprising a hook body and a support frame. The support frame includes a ring body, two support rods, a spindle, and a wedge block. The ring body is connected to the spindle, the hook body passes through the ring body, and the spindle is connected to the wedge block. The two support rods are symmetrically arranged about the wedge block, and the wedge block is slidably connected to the support rods. The two ends of the support rods are a movable end and a holding end, respectively. The movable end is hinged to the spindle, and the holding end is inclinedly connected to a locking block.

[0004] Furthermore, a pressure plate is connected to the outer wall of the wedge block, and the pressure plate is in contact with the outer wall of the support rod.

[0005] Furthermore, a through groove is provided on the support rod.

[0006] Furthermore, a bottom support plate is provided at the bottom of the holding end.

[0007] Furthermore, the wedge block is connected to the end of the hook body via a threaded ring.

[0008] Furthermore, the relative tilt angle between the locking block and the support rod The temperature is 110-130 degrees Celsius.

[0009] The beneficial effects of this utility model are as follows: the connection between the hook and the support frame forms a force transmission path. During hoisting, the weight of the shaft causes the wedge block to slide and push the support rod to rotate. The locking block clamps the inner groove, and the weight of the hoisted object enhances the connection strength. The lever structure stabilizes the hanging shaft. The pressure plate on the outer wall of the wedge block fits against the support rod, increasing the sliding friction of the wedge block, suppressing swaying and offset, and ensuring that it pushes the support rod to rotate stably and accurately, allowing the wedge block to slide stably under the weight of the shaft. The through groove on the support rod reduces weight while ensuring structural strength, thus reducing the load on the hoist. The load is reduced, and the resistance to entering the electroplating bath is also reduced; the bottom plate at the bottom of the clamping end limits the range of movement of the wedge block, preventing overtravel and disconnection from the support rod; the wedge block is connected to the hook body through a threaded ring, which facilitates disassembly and maintenance and is suitable for the highly corrosive environment of electroplating; the clamping block is inclined at 125 degrees to the support rod, and the force is optimal after being clamped into the inner groove. Compared with other angles, it is subject to less shear force and lateral force, and the external force is evenly distributed to avoid connection failure. This maximizes the connection strength between the clamping block and the groove, and ultimately ensures the stability of the shaft during the electroplating process without affecting the electroplating quality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 This utility model provides the following technical solution: a hanging device suitable for heavy items, including a hook body 1 and a support frame. The support frame includes a ring body 2, two support rods 3, a spindle 4, and a wedge block 5. The ring body 2 is connected to the spindle 4. The hook body 1 passes through the ring body 2. The spindle 4 is connected to the wedge block 5. The two support rods 3 are symmetrically arranged about the wedge block 5. The wedge block 5 is slidably connected to the support rods 3. The two ends of the support rods 3 are a movable end 6 and a holding end 7, respectively. The movable end 6 is hinged to the spindle 4. The holding end 7 is inclinedly connected to a locking block 8.

[0019] In the above structure, when hoisting a heavy shaft 13, the weight of the shaft 13 will cause the wedge block 5 to slide on the support rod 3, pushing the support rod 3 to rotate around the movable end 6. The locking block 8 further locks the inner groove of the inner wall of the shaft 13. The pressure generated by the weight of the hoisted object enhances the connection strength between the locking block 8 and the inner groove. In conjunction with the lever structure of the support rod 3, the shaft 13 is stably hung, ensuring that the shaft 13 will not be affected by shaking during the electroplating process.

[0020] In this embodiment, the outer wall of the wedge block 5 is connected to a pressure plate 9, and the pressure plate 9 is in contact with the outer wall of the support rod 3.

[0021] With the above structure, the pressure plate 9 fits snugly against the support rod 3, increasing the friction of the wedge block 5 during sliding, suppressing swaying and offset during the sliding process, and ensuring the stability and accuracy of the wedge block 5 in pushing the support rod 3 to rotate. When hoisting a heavy shaft 13, the weight of the shaft 13 causes the wedge block 5 to be under force. At this time, the pressure plate 9 ensures the stable sliding of the wedge block 5.

[0022] In this embodiment, the support rod 3 is provided with a through groove 10.

[0023] In the above structure, the through groove 10 effectively reduces the weight of the support rod 3 while ensuring the structural strength of the support rod 3, and can also reduce the resistance when the hanger enters the electroplating bath.

[0024] In this embodiment, a bottom support plate 11 is provided at the bottom of the holding end 7.

[0025] With the above structure, the bottom support plate 11 can limit the movement range of the wedge block 5, prevent the wedge block 5 from moving beyond its travel range, and avoid breaking its connection with the support rod 3.

[0026] In this embodiment, the wedge block 5 is connected to the end of the hook body 1 via a threaded ring 12.

[0027] With the above structure, the threaded ring 12 connects the wedge block 5 and the hook body 1, which facilitates the disassembly and maintenance of the two. In the highly corrosive environment of the electroplating industry, it is convenient to regularly inspect and replace the hanger components.

[0028] In this preferred embodiment, the relative tilt angle between the locking block 8 and the support rod 3 is... It is 125 degrees.

[0029] Using the above angle, the locking block 8 is inclined at 125 degrees to the support rod 3. After being locked into the inner groove of the shaft 13, the force is optimal. Compared with other angles, the locking block 8 is subjected to less shear force and lateral force at 125 degrees, and the external force is evenly distributed, avoiding connection failure and maximizing the connection strength between the locking block 8 and the groove.

[0030] This hanger is used to mount heavy shaft 13.

[0031] Hanging principle: When the hanging device is working, the gantry crane in the factory controls the descent of the hanging device, aligning the locking block 8 with the inner groove of the inner wall of the shaft 13. When the locking block 8 is aligned with the inner groove, the gantry crane applies force to drive the hook body 1 to rise. The hook body 1 pulls the inclined wedge block 5. During the sliding process with the support rod 3, the inclined wedge block 5 is kept stable by the outer wall pressure plate 9. At the same time, it pushes the support rod 3 to rotate around the movable end 6, so that the locking block 8 of the locking end 7 of the support rod 3 is locked into the inner groove. The inclined locking block 8 is tightly attached to the inner groove wall to form a stable lever locking structure, thereby realizing the hanging and lifting of the shaft 13.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
